Question

我有一个ModelSerializer：

class PublicNetwokSerializer(ModelSerializer):
    """
    PublicNetwok
    """
    class Meta:
        model = PublicNetwok
        fields = "__all__"

该模型如下：

class PublicNetwok(models.Model):
    name = models.CharField(max_length=12)
    desc = models.CharField(max_length=24)
    ...

你知道如果我使用ModelSerializer，我将获得所有键值，如下面的：

[
 {
  "name":"xxx",
  "desc":"xxx",
 },
 {
  "name":"xxx",
  "desc":"xxx",
 }
]

但我想将密钥desc更改为description，在Django-Rest-Framework中如何访问它？

Answer 1

class PublicNetwokSerializer(ModelSerializer):
    description = serializers.SerializerMethodField('get_alternate_name')

    class Meta:
        model = PublicNetwok
        fields = ('name', 'description')

    def get_alternate_name(self, obj):
        return obj.desc

如何替换Serializer中的密钥名称？
